Flare stars across the H-R diagram

From Kepler data, we show that the incidence of flares on stars drops by only a factor of 4 from K-M dwarfs to A-F stars. Allowing for visibility effects, this implies that the...基于开普勒（Kepler）望远镜的观测数据，我们的研究表明，恒星耀斑的发生率从K型至M型矮星（K-M dwarfs）到A型至F型恒星（A-F stars）仅降至原有的四分之一。若考虑观测视见效应的影响，这一结果意味着……
